Pick AFL++ if…
AFL++ is for developers and security practitioners fuzzing source-available software, binary-only targets, network services, or GUI programs. Users should be comfortable with its AGPL obligations or the separately listed commercial license.
Pick ClusterFuzz if…
ClusterFuzz suits software teams that need automated fuzzing and crash triage, especially teams able to operate the required infrastructure. Local deployment is an option for Linux and macOS users.
